How to know which binding is running/used?

I have a qeustion about binding:

bundle:list shows:
203 | Installed | 80 | 2.1.0.201705192246 | ZWave Binding
209 | Resolved | 80 | 2.1.0.201706222153 | ZWave Binding

My question is. Which one is used and why I have two of them in the list?

Not one of them is used, it needs to be in state “Active”

openhab> bundle:list |grep -i zwave
 10 │ Active   │  80 │ 2.2.0.201710012213     │ ZWave Binding

So do a bundle:list |grep -i zwave and you will probably find your active zwave binding …

I guess you installed them at some point in the past. Check your addons folder if any *.jars are present.

Thanks, now it is clear, I had a second binding installed. And now it is active too.
